ABSTRACT DICER1 ‐mutated thyroid lesions can range from indolent to aggressive neoplasms. Infarction has been recently described as a histologic feature of DICER1 ‐mutated thyroid nodules. In this case report, we presented a DICER1 ‐mutated nodule which presented predominantly with debris in the fine needle aspiration (FNA) specimen and was confirmed on surgical resection to be a near total infarcted nodule. To the best of our knowledge, this is the first cytopathology report of a DICER1 ‐mutated thyroid lesion presenting as an infarcted nodule. Awareness of the features described herein may help prevent both overdiagnosis and underdiagnosis in the evaluation of thyroid nodules via FNA.
